Thought I would give an update, I replaced the plugs, coil, plug wires, rotor and cap. Then took a fairly long test drive, with hard acceleration runs. It seems to be fine. Now, I need to address what seems to be rich running during start up. I did not find any completely fouled plugs, per say, but the plugs had a strong gasoline odor. This sounds like the cold start switch, I'm thinking.
